Thank you for doing your homework, Ryan.
REMINDERS:
* We used EITHER instead of too if the statement is negative.
Examples:
Positive - I like yellow too.
Negative - I don't like yellow either.

* Be careful with your conjunctions. BUT is used before an added statement, usually something that is different from what you have said before.
